7. Restoring Factory Calibration: lpc Comand
The calibration coefficients can be saved in the camera in 5 different ―sets‖, num bered from zero to four.
The factory calibrations are saved in set zero and you cannot overwrite the ―zero‖ settings. To op erate in
―set zero‖ you u se the ―set set num ber‖ or ssn command by typing ssn 0. Next, to restore the factory
coefficients, you need the ―load pixel coefficients‖ or lp c com m and . Unfortu nately, this com m and w as
not d ocumented in the User‘s manual you have and this will be upd ated in the fu tu re revision s. The
description is as follows:
Loading a Saved Set of Coefficients
Purpose:
Loads a saved set of pixel coefficients for the current direction. A
factory calibrated set of coefficients is available.
Syntax:
lpc
Notes:
Available in TDI mode only.
To restoring the camera calibration settings, then the follow ing sequence is this (using the ―/ / ‖ to ad d
comments):
ssn 0 / / sets the camera set number to the factory set
lpc / / loads the factory coefficients
ssn 1 / / sets the user set number
wfc / / saves the fpn coefficients
wpc / / saves the prnu coefficients
This sequence should restore your coefficients back to the factory settings.
Note that this restoring process will not restore the factory gain settings, cameralink modes, sync
frequency, and any other camera settings you may have changed and then saved using the wus
command. These settings are all restored using the rfs command which must be followed by the wus
command to make them ―rem embered ‖ for the next p ow er cycle.
